MACHINE FOR SETTING LAClNG-HOOKS SPECIFICATION forming part of LettersPatent No. 659,746, dated October 16, 1960.

T0 all whom it may concern:

Be itknown that I, ROBERT F. HARGRAVES, a citizen of the United States,residing in the city of Providence and State of Rhode Island, haveinvented certain new and useful Improvements in Machines for SettingLacing- Hooks, of which the following, with the drawings hereby made apart hereof, is a descrip tion and specification.

The portion of this class of machines which has been the subject of mostinventions is the mechanism employed to bring the lacinghooks intoposition for setting, and the principal parts of my presentinventionhave reference to this mechanism. In improving that mechanism I believeI have also obtained a much simpler machine to make and operate in otherrespects.

Referring to the drawings, Figure 1 is a side elevation of my machine.Fig. 2 is a perspective view of a lacing-hook such as this machine isdesigned to set. Fig. 3 is a top plan view of the hopper to contain thehooks and the track or raceway along which they pass to the settingmechanism. Fig. 4is a top plan of the setting-tool. Fig. 5 is a verticalsection of the same tool on line 5 5 of Fig. 4. Fig. 6 is a top plan onsection-line 6 6 of Fig. 1. Fig. 7 is a top plan of a portion of Fig. 6,showing a portion of the setting mechanism in a different position. Fig.8 is an enlarged sectional view of the stop or detent on sectional line8 8 of Fig. 7. Fig. 9 is a front elevation of the raceway, showing thestop hold ing back the hooks. Fig. 10 is a longitudinal section showingthe cam for throwing up the setting-tool. Fig. 11 is a longitudinalsection showing the cam for operating the carrierblock and mechanism forplacing the hook in position for setting. Fig. 12 is a detail section ofcarrier-block, showing eccentric for adjusting the travel of thecarrier-block; and Fig. 13 is a top plan on sectional line 13 13 of Fig.12.

The machine consists of a suitable framework or standard A, Fig. 1,having an upright head or bracket B, and in the front of this head ismounted the setting-die M, made adjustable vertically by thescrew-threads and nuts M. v (See Fig. l.) The shaft C (see Figs; 1 and6) is driven by the pulley D, Fig. 6, and there are mounted upon it tobe driven thereby the circular plates E and F, Fig. 6, each havinggrooved cams out upon their respective surfaces, (see Figs. 10 and 11,)and also the beveled gear G, Fig. 6. This beveled gear G,by means of theother gear running into it and the shaft H, (see Figs. 1, 3, and 6,)operates the mechanism in the reservoir or hopper I, Fig. 3, for pickingup the lacing-hooks and placing them upon the raceway J. The cam in thesurface of plate F operates the lever L to throw up the setting-tool onthe end of the spindle N, Figs. 1 and 10, and the cam in the plate E,Fig. 11, operates the carrierblock P, Fig. 6, as will be hereinaftermore specifically described.

It will be understood by referring to Figs. 1 and 3 that thelacing-hooks in the reservoir I are brushed upon the end of the racewayJ by the revolving brushes therein and slide down this raceway bygravity. It will be observed that these hooks are then in such aposition that their shanks are up. The end of the track J is shown inFigs. 6 and 7. The hooks are arrested in their downward course by thespring-controlled stop or detent 0, (see Figs. 6 and 7 and the enlargedviews thereof in Figs. 8 and 9,) which is readily pushed down out of theway by the hook when moved by the mechanism carried by the carrierblockP. The setting-tool consists of the spindle N, with a groove across itsend, and a plate N, arranged as a continuation of the raceway J, (seeenlarged views, Figs. 4 and 5,) this plate N serving as an anvil uponwhich the hook is set when driven by the lever L against the setting-dieM, Figs. 1 and 10, mounted in the head B. For placing the hooks one byone in position for setting the carrier-block P slides across themachine in slideways cut for it, as shown in Figs. 1, 6, 7, and 11. Thisplate P is given its motion by means of the sliding rod E, Fig. 6, whichin turn is given motion by the grooved cam in the plate E. Aconnecting-rod E connects E with the block P. A finger P, Figs. 1, 6,

and 7, is mounted in a couple of projections elbow is held in the normalposition (shown in the drawings) by the spring R" pressing its upper armagainst the pin R and carries upon its other arm a wedge-piece R whichis of such an elevation that it is in the path of the roller P in thefinger P when the latter is carried laterally to the right by thecarrier-block P.

The machine operates as follows: The hooks after being brushed upon theraceway J slide down by gravity until they come into contact with thestop or detent O. The carrier-block P is moved laterally to the right bythe cam E and the connections between them, and the roller P is therebybrought into contact with the wedge R and by rolling upon its inclinewithdraws the finger P against the spring P", so that it will pass freeof the hook resting against the stop 0. The wedge R is so proportionedthat the roller P reaches its right-hand end when the pointed end of thefinger P is back of the hook resting against the stop 0, when the rollerpasses oif the wedge R and the finger is driven by the spring betweenthat hook and the next one behind, the end of the finger being sharpenedfor this purpose. When the carrierblock P moves to the left, the fingerP car ries the hook from the raceway onto the anvil N of the spindle N,pressing it back of the spring N, which serves to hold the hook inposition, while the spindle later is driven upward. During this motionto the left of the carrier-block P the roller- P passes under the wedgeR, thereby turning the elbow R, to which the wedge is attached, upon itspivot R and permitting the finger P to return to its first position. Thetwo extreme positions of these parts are shown in Figs. 6 and 7. Themovements of the two cams E and F are so timed that camF will drive thespindle N upward and set the hook on the anvil N at its top by drivingit upon the setting-die M while the finger P is out of the way and willreturn the spindle N to its lower position before the finger P can pushanother hook so far forward as to come upon the anvil-piece N. Inpractice the operator will hold the work in which the hook is to be setunder the die M and the machine drive the hooks upward successivelythrough the work and set them upon the die.

In Figs. 12 and 13 are shown a cam connection between the sliding rod Eand con necting-rod E, whereby the position to which the finger P willpush the hooks can be accurately adjusted.

I claim as my invention 1. In a machine for setting lacing-hooks, thecombination of a track along which the hooks may slide, and a device forseparating the hooks one from another and placing them in position forsetting, consisting of a carrier-block and mechanism to move it, afinger mounted to slide bodily on said block transversely thereof,mechanism by which the finger is removed from the path of the hooks whenthe carrier-block is moved in one direction, and mechanism which placesit in the path of the hooks to move them when the carrier-block is movedin the opposite direction. a
